You can create a method to handle it properly. Note this following is in C#/Java mixed style, you need to tweak a bit to compile.

private boolean isAttribtuePresent(WebElement element, String attribute) {
    Boolean result = false;
    try {
        String value = element.getAttribute(attribute);
        if (value != null){
            result = true;
        }
    } catch (Exception e) {}

    return result;
}

How to use it:

WebElement input = driver.findElement(By.cssSelector("input[name*='response']"));
Boolean checked = isAttribtuePresent(input, "checked");
// do your assertion here
